| Fit | Moderate |
|---|---|
| When to plant | 2 Mar 2027 – 22 Mar 2027 opens in 22 weeks |
| Expected harvest | about 0.7 t/ha |
| Harvest | From 10 Jun 2027 to 19 Aug 2027, depending on the planting date |
| Ready to harvest | 100–150 days after planting |
| Work it takes | 75–156 days per hectare, by hand |
Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oued Sly is close to normal, so these dates match the pattern the area usually follows.
Planting after 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Oued Sly
| Rain and temperature | 60% |
|---|---|
| The soil | 88% |
| The lie of the land | 45% |
For lablab in Oued Sly, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The 2026/27 season in Oued Sly
| When the rains are expected | October 2026 to April 2027 |
|---|---|
| Rain in a typical year | About 374 mm |
| This season's rain | Rain close to usual — plan around about 374 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |
| What that supports | enough rain for one short crop, and only if timed to it, warm, with a cool spell that slows winter growth |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 87% of this area. |
| 87% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 166 growing days · about 360 mm · October to April |

What lablab needs to grow here
| Soil it likes | well-drained sand, sandy loam, loam, clay loam or clay soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 7.5 |
| Spacing | 75 cm between rows, 30 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow lablab in Oued Sly
| Nitrogen (N) | About 26 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 6 kg per hectare |
| Potash (K₂O) | About 9 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 75–156 days per hectare, by hand |
These are the nutrients a lablab crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
